Lewis Hamilton has vowed no quarter will be given in his pursuit of this season's Formula One world title despite announcing his defection to Mercedes on Friday.
Hamilton is to end his 14-year association with McLaren at the end of this season, joining Mercedes on a three-year deal worth £15million per year. The move now draws into question his dedication to McLaren for the rest of the campaign, which has six races remaining, starting in Japan next Sunday.
But although trailing Ferrari's Fernando Alonso by 52 points with 150 still up for grabs, Hamilton said: "In terms of the championship, there's nothing to really be gained by analysing the points tables. From now on, it's simply gloves-off. As in Singapore, I'll come out fighting, and I'll just be hoping for a better result next weekend."
That follows Hamilton's retirement at the Marina Bay Street Circuit on lap 23 with a gearbox failure when comfortably leading the race, denying him what would have been a third victory in four grands prix.
That, though, had no bearing on his decision to leave McLaren, with Hamilton telephoning team principal Martin Whitmarsh on Wednesday to deliver his answer after being set a final deadline.
